Professional wind tracking systems
Thanks to an active wind-measurement
system that processes velocity and
direction data, the azimuth drive
always rotates the nacelle into the
most efficient position.
Designed for maximum safety
The turbine is designed and built
with multiple safety systems such
as a remote control via a VPN
connection and hydraulic brakes,
as well as a safety ladder and a
stand ring for use by technicians.

STRONG AND SILENT
Entirely manufactured in Germany, the Lely Aircon 10 is an
engineering masterpiece that is the result of many years of
market experience. Right from the beginning, the objective was
to develop a small wind turbine with strong performance, new
technology and safety systems comparable with larger wind
turbines.
A special priority was to design the quietest turbine on the
market.
Today, with over 200 installations worldwide, the concept is
both accepted and proven.
Ultra-durable gearless
permanent synchronous
generator
The unique, compact design
with minimum moving parts has
proven to be ultra-durable in all
kinds of environments worldwide.
Aerodynamic blades and
nacelle housing design
The blades and the nacelle were
designed to be aesthetic as
well as functional, and obtain
maximum yield from the wind.
Exceptionally quiet and stable
wind tracking thanks to active
azimuth drive
Due to an active wind-measurement
system that processes velocity and
direction data, the azimuth drive
always rotates the nacelle into the
most efficient position.

ZZZZZZ Sleep well!
The aerodynamic blade shape, the absence
of gears and the unique inverter technology
for low noise frequency make the
Lely Aircon 10 the quietest turbine in the
market place. Even at wind speeds above
10 m/s, the turbine remains exceptionally
silent. This means that the turbine can be
located relatively close to urban areas.

Distance
Distance fromnacelle
from nacelle(m)
(m)
The Lely Aircon 10 is virtually inaudible at a distance of 60 metres (slant angle from nacelle).
Aerodynamic blade shape
The blades were custom designed for the Lely Aircon 10. The design and
operation ensure the best results in terms of both low noise and maximum
yield. The blade was designed according to the aerodynamic stall function,
which is one of the safety systems that regulate speed and avoid excessive
speed.
Unique inverter technology
Due to direct synchronisation of one inverter to the generator, noise from
the electrical system is reduced significantly.
No gears, low noise
The generator is equipped with permanent synchronous technology which
makes gears unnecessary and therefore helps limit noise.

The Long-term
investment
The return on investment is dependent
on the incentives available in your
country. The turbine is certified by the
Microgeneration Certificate Scheme
(MCS). In the United Kingdom, MCS
accreditation ensures entitlement to
generous tariffs for small wind turbines.
Your own turbine will reward you with
all the energy generated and exported to
the grid (fixed tariffs for twenty years). In
addition to the income from generation
tariffs and export tariffs, you will also
benefit from savings to your energy bill. In
Germany, the Renewable Energy Act also
offers incentives for the feed-in of energy
in to the grid.
Return on your investment
Depending on the wind conditions at your site, the
development of electricity prices and the level of
self-consumption, it is possible that you can realise a
return on your investment in eight to ten years. The
Lely Aircon 10 has a design life of more than twenty
years. This means you will see a comfortable return on
your investment in the long term.
If you need additional information about market
incentives available in your country, we would be
pleased to help you. We can also provide you with a
full payback period analysis in accordance with your
location.

Quality matters
Since the original development of the Lely Aircon 10, the major objective has been
to ensure the quality and the reliability of the turbine. The turbine was developed
nearly 17 years ago, and has been in serial production since 2003. Design,
development and manufacturing is carried out 100% in Leer, Germany. The
Lely Aircon 10 turbine has sophisticated, leading-edge technology which is
comparable to large utility-scale turbines. In terms of control, mechanical and
safety features, the engineering is superb. The power electronics synchronise and
deliver a perfectly controlled wave form to the grid.
With its unique design incorporating the minimum of moving parts, the
Lely Aircon 10 only requires a brief and basic annual inspection and lubrication
service. To facilitate cost-effective servicing, the service technician can access the
nacelle by climbing the safety ladder that is a standard feature.
No gears, low costs
Minimal moving parts in the turbine means huge benefits in terms of reliability and
durability, as well as keeping service costs to a minimum. This in turn results in low
ownership costs during the expected lifetime of over 20 years.
Lowest cost of ownership
The Lely Aircon 10 is an extremely durable wind turbine. Thanks to its long lifetime
and low maintenance costs, the investment over the total lifetime is much lower
than other turbines.
PAYBACK PERIOD EXAMPLE, UK
Total turbine production per year: 25,000 kWh
(Average annual wind speed of 6 m/s on 30 m tower)
Annual energy production by turbine 25,000 kWh x 0.281 = £ 7,025
Savings from not buying energy from the grid 15,000 kWh x 0.12 = £ 1,800
Export of energy to the grid 10,000 kWh x 0.03 = £ 300
Annual income £ 9,125
Sum of income over 20 years £ 182,500
Turbine cost £ 67,000
Payback period approx. 7 years

GENERATOR
The generator is based on direct drive
permanent synchronous technology. The
generator technology is owned and patented by
Lely Aircon. A unique coil and permanent magnet
design ensures that the generator is extremely
compact and provides maximum energy density
and thus performance.
INVERTER
Inverter technology, together with Lely Aircon’s uniquely
developed software control, has multiple advantages
regarding optimisation of noise levels and the power
curve at your location.
8
WIND
Wind is actively measured at the top of the nacelle with an
anemometer for the measurement of wind velocity and a
wind vane for tracking wind direction. This measurement
data is processed and assessed by the turbine control
system. The obvious advantage of this real-time
measurement of data is that the nacelle is always rotated by
the azimuth drive into the ideal position to achieve
maximum efficiency.
SAFETY
Safety of the complete turbine system is paramount.
Therefore the Lely Aircon 10 includes, as standard, multiple
safety systems. The blades of the Lely Aircon 10 are not
only designed for maximum yield, they are also designed
according to the ‘Stall principle’. If the wind speed at the
tips is too high, a controlled stall is forced to reduce the
rotational velocity. In addition, the turbine includes an
active hydraulic brake system, multiple temperature sensors
and a shake contact in case of imbalance at the rotor. Every
turbine system is supplied with a certified ladder and stand
platform for maintenance purposes.
